Problem

-If the JMC component could not be loaded or redeployed after B2Bi was updated and the following stack trace is thrown in the trace viewer:

• AutoReg:887: Failed to update registry: The component registry entry is referred by one or several enabled activity stages in main configuration server
• AutoReg: 895:Failed to remove Component 'Atribute classifier component' from main configuration server

• AutoReg:936:Failed to add Component 'Atribute classifier component' in main configuration server
• AutoReg:936: Failed to add Component Content Length check classifier component JMC' in main configuration server

Resolution

1. Check the component registry on the B2Bi server > Manage components if the target resources are no longer available in the Integration Engine
2. Verify if the invalid component is linked with a Service > Metadata profile or if another processing configuration item is chained.
3. Remove any connection from Services, Metadata profile, etc with the affected JMC component
4. Delete the jar file from $SHARED_LOCAL\java\component and its correspondence tag file
5. Copy the jar file back to $SHARED_LOCAL\java\component
